• Rice Cultivation Duration Is Associated with Changes in Potential CO2 Production, Q10, Enzyme Activity, and Microbial Diversity in Saline–Alkali Soils (2026) · Agriculture · doi

  The effects of long-term rice cultivation and warming on carbon cycling responses in saline-alkali soils are not well understood. There is a lack of studies investigating the impact of rice cultivation duration on potential CO2 production and microbial diversity in these soils. The relationships between rice cultivation duration, soil temperature, and CO2 production are not clearly understood.
